What Others Think

really the shell should be able to cope with such a task ... without the need for excessive pipes ... eg, with zsh: print ${$(ip -o -4 addr show eth0)[4]:t} however ... you might simplify the above by using awk exclusively: ip addr show |awk '!/127\..*/ && /inet/{a=split($2,cidr,"/") ;print cidr[a]}'
